Constructing Measures introduces a way to understand the advantages and disadvantages of measurement instruments, how to use such instruments, and how to apply these methods to develop new instruments or adapt old ones. The book is organised around the steps taken while constructing an instrument. It opens with a summary of the constructive steps involved, each step is then expanded on in the next four chapters. These chapters develop the "building blocks" that make up an instrument--the construct map, the design plan for the items, the outcome space, and the statistical measurement model. The next three chapters focus on quality control. They rely heavily on the calibrated construct map and review how to check if scores are operating consistently and how to evaluate the reliability and validity evidence.
Tightly bound, with clear text on clean pages and bold charts, diagrams, graphs and formulae, the book includes a cd-rom, held in a clear pocket at the end of the book, also in pristine condition.
